Question

Correct the mistakes and rearrange the given flow chart of hearing process

Answer 1

Hint:Hearing is defined as a process by which our ear transforms the sound vibrations into nerve impulses that are carried to the brain. In the brain the nerve impulses are interpreted as sounds.

Complete answer:
Ear is a very sensitive organ of the human body. Parts of ear include-External ear that consists of pinna.
Tympanic membrane is also called an eardrum,Middle ear consists of ossicles and the inner ear has cochlea.
Mechanism of hearing is:-
The sound waves enter the outer ear and reach the eardrum through the ear canal Eardrum sends it to the three tiny bones called ear ossicles in the middle ear.
The amplification of the sound is done by the bones in the middle ear. Then it is sent to the inner ear or cochlea through the oval window.
The vibration activates the tiny hair in the ear. The hair cells of the organ of Corti convert the sound vibrations to nerve impulses in the fibres of the cochlear nerve.
The auditory nerve carries the electrical signal to the brain.
The electrical signals are interpreted by the optic lobe of the forebrain.
 So the correct answer is
Ear canal → Eardrum → Ear ossicles → Oval window → Cochlea → Auditory nerve

Note: The human ear is most sensitive to frequencies of 1000-4000Hz. The human ear can distinguish the different aspects of sound such as pitch and loudness. Sounds are produced when vibrating objects produce the pressure pulses of vibrating air molecules called sound waves.
